AUTOMOBILE-SPRING.

' Application filed November 13, 1907. Serial No. 402,007.

Be it known that I, WILLIAM RUSSEL RANTZ, a citizen ofthe United States, residing at Greenville, in the county` of Darke and Stateof Ohioyhave invented a new and useful Improvement inAutomobile-Springs, of which the following is a speciicatipn.

This invention relates torsprings especially designed for use in connection with antonio-- biles, but vadapted also for use. with vehicles of all kinds. i.

The invention consists of the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which Figure 1 is a sectional side view of one ,of the springs. F'g. 2 is a front view, anrangl'e beam being shown in cross section. Fig.' 3 is a plan view lof a set of springs. l Fig. 4 is a side elevation showing 'a slight modiiication. Fig. 5 is a section on the line 5-5 of Fig. 4.

In constructing the invention I secure a cylinder 1 by means of a split base 2te-san axle 3. It is to be understood that in applying the device to an automobile theparts hereinafter described are du licated upon opposite sides and also at the ontand rear. The cylinder 1 is provided 'with oppositely .extending bracket arms -4 carried by a flanged cap portion 4? of the Cylinder and within the cylinder is arranged a piston 5 I which is provided with a piston rod l7 about which is coiled a spring 6 which bears upon the cap 4a and upon the piston 5. To upturned end portions vof the arms 4 are pivoted intermediate their ends S-sha ed levers 8 the inner ends of which are loose y connected to a block 9 carried by the piston rod 7.y Preferably, I prefer to bifurcate the ends of the block 'and slot the bifurcated portion and pass pins 8a through the levers`8, said pins working in the -slots of thegblock. To any suitably constructedl portion of the body 10 of the vehicle, I secure by any suitable means cylinders 1 1 in which work pistons 12 provided with piston rods 12a and with springs 12b corresponding to the springs 6. The lower ends of the piston rods 12a are bifurcated and iit over the end ortions of the levers 8 which are slotted as s own at 8h, the

. pivot pins securing the piston rods to said levers passing loosely through the slots. In

thepiston 7 instead of being connected directly to the block itself. Otherwise the construction isthe same as that already d escribed.

It will be noted that a spring device constructed as shown and described will give the yielding action of a spring board, all jars being taken u by the springs 6 and 12b and the strain an stress upon said springs being to a greatextent removed by the yielding or rocking motion of the levers 8 or 13, there beingno rigid connections between any portion of the body of the vehicle and the axles.

It will be obvious that 'the parts may be changed in shape and size to adapt them to cars of different types and sizes and also that any suitable form of bracket or hanger may be employed to connect the device to the style of body used.

I-Iaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A device of the kind describedcomprising 'three spring pressed iston rods, one of said rods being arranged elow and between the others, and curved levers pivotally connected intermediate their ends and having their end portions loosely connected to said piston rods.

2. In a device of the kind described,.three 'cylinders, one cylinder being carried by a vehicle axle and two by a vehicle body, bracket arms supported from the vehicle axle, and levers pivoted upon said arms, spring pressed piston rods in said cylinders,

and means loosely connecting the inner ends 'Ill der, bracket arms carried by the axle cyl t inder, and S-shaped levers pivoted upon said arms, the ends of sa@ levers being loosely connected respectively to the block Lof the axle piston rod and to the lower ends of the other piston rodsi WILLIAM RUSSEL RANTZ.-
